Frequently Asked Questions (FAQs)
Here are some frequently asked questions. If you have additional questions or want to talk further about this project, please email Louise@saint-marys.org and she will get you in touch with the appropriate person to help you.
Q: Why do we need this new system?
A: During COVID, we discovered that our building ventilation is inadequate, increasing the risk of COVID and other respiratory viruses spreading. A new HVAC system is an important part of safely returning to our church. This is the primary reason we are installing the new system. An added benefit of adding air conditioning is that it will help us better adapt to the changing climate, such as the rising summer temperatures and more frequent heat waves.
Q: What is meant by inadequate ventilation?
A: When building ventilation is inadequate, there is not enough fresh air being brought into the building. This means that there is currently a low air exchange rate (rate of fresh air coming in and “stale” air going out). We need more fresh air to dilute or flush out contaminants. Without proper ventilation these airborne contaminants, like cold and flu viruses, can become concentrated within the space. Additionally, lack of fresh air can lead our worship space to feel stuffy and stale.
Q: What does HVAC stand for?
A: H.V.A.C. stands for heating, ventilation, and air conditioning. An HVAC system is designed to provide thermal comfort and acceptable indoor air quality.
Q: What is a heat pump?
A: A heat pump is an energy efficient method for heating and cooling air. A heat pump works by transferring heat. In cooler months, a heat pump pulls heat from the outdoor air (yes, there is still heat to be pulled out of cold air!) and moves it inside. In warmer months, a heat pump pulls heat out of indoor air and releases it outside, leaving your indoor air cooler. Heat pumps are powered by electricity and transfer heat using refrigerant to provide comfort all year round.
Q: What is an ERV?
A: ERV stands for Energy Recovery Ventilator. An ERV is a ventilation system that increases energy efficiency by capturing some of the heat or cold from the air you are getting rid of and transfers it to the air you are bringing in.
Q: Why get an ERV and a heat pump?
A: The combination is the most energy efficient option available to both increase air exchanges while keeping the air at a comfortable temperature. The ERV will support the heat pump by making it have to work less hard on the hottest and coolest days.
Q: What are the environmental benefits of this system?
A: By combining two energy efficient technologies in our new system, we are lowering the amount of energy needed to run it. By installing a totally electric system, we can reduce our dependence on carbon-producing fossil fuels. More than 80% of Eugene’s electricity is from carbon-free sources such as hydropower and wind. Due to recent legislation in Oregon, the percentage of our electricity that comes from renewable sources will increase. Additionally, this new system will allow us to start moving away from our current natural gas-powered boiler, reducing our direct use of fossil fuels in our building.
Q: I want to give but I don’t have the money right now.
A: Thank you! We appreciate your commitment to St. Mary’s and are happy to work with you to find a time that works for you. Ideally, we would like to receive the funds by the end of the year, but we can receive the funds in 2022. Please contact Lana Johnson, Finance and Records Manager, Lana@saint-marys.org, if you need to discuss the timing of your gift.
